Recently, Shengxi Oilfield Plant Brigade Technology Brigade Technical Association successfully developed a new type of anti-blasting flushing sand valve. The application of this tool has better protected the oil and gas layer, achieved no pressure killing operation, and reduced unnecessary rework caused by accidents. , to improve the production of timeliness.

When this group used the blowout-proof sand plugging valve in the West Zhuzhuang area, there were 2 wells in the 7 wells in use, which caused delays in the construction period due to the lack of openable plugs, which affected the timeliness of production. To this end, the technical association staff carried out a careful analysis of the reason why the blowout flushing sand valve could not be opened. Through anatomy and scrutiny, the structural design was re-engineered. The qualified petroleum machinery company limited the processing, and a new type of blowout prevention sand blocking valve came into being. . The tool has reliable performance and has been tested and used in 6 wells with non-compressed wells. They all open the plugs normally within the 8-10 MPa rated pressure range, achieving normal operations such as circulating sand washing, washing wells and acidizing, and improving Quality of work. At present, the tool has been widely applied in oil wells with various wells that do not kill wells, and the innovative and effective results have been remarkable.
